Abstract (en)

This invention relates to a pneumatic rubber tire having a tread of a cap/base layered construction wherein said tire contains a first component as a tread cap layer having a running surface and at least two additional tire rubber components, wherein said tire components comprise rubber compositions which contain a maximum of 50 phr of reinforcing filler comprising a maximum of 30 phr of rubber reinforcing carbon black. In one aspect, a purpose of such maximum of 30 phr of rubber reinforcing carbon black for said plurality of tire components is to promote a relatively low hysteresis property within said tire via such components to thereby promote relatively low rolling resistance for a pneumatic tire which contains such components. In practice, such additional tire components may be, for example, outer sidewall rubber layer, apex, chafer, belt ply and carcass ply components.
